software piracy

Anti-piracy

It includes, but is by no means limited to, the combined efforts of corporate associations (such as the RIAA and MPAA), law enforcement agencies (such as the FBI and Interpol), and various world governments to combat copyright infringement relating to various types of creative works, such as software, music and films. These measures often come in the form of copy prevention measures such as DRM. Nearly 90% of college students download music illegally making them the group of people who download music the most illegally.

Metal Gear Solid required a piece of information from the game's jewel case for the player to progress after a certain point, making pirated copies effectively worthless without the original jewel case.
